01 · Scan
Scan the key
A sensor in the lock cylinder scans its physical properties. Nothing is attached or engraved.
// Identity from physical properties
Objects have fingerprints. We read them.
Every key has unique physical properties. Our sensor scans them, so the key in your pocket becomes a digital pass. No RFID, NFC or chips, no batteries.
01 · Our solution
Swap one cylinder. Keep every key.
It needs no RFID, NFC, chips or batteries to tell what makes each key unique.
- Standard cylinder size
02 · Your key
Your key stays the same.
03 · The scan
The cylinder scans its physical properties.
04 · Approved
Approved keys open.
Lost or stolen
A lost key is switched off in one click.
Blocked keys don't open.
Technology
Identical keys. Different fingerprints.
Two keys cut on the same machine look identical, but their physical properties are not. We scan that difference and turn it into a fingerprint.
02 · Fingerprint
Create a fingerprint
Our AI turns the scan into a signature unique to that one key.
03 · Match
Open, or stay shut
The lock checks that exact key, not just its cut, and opens only for approved keys.

Physical keys. Digital control.
You give a key to your cleaner, but only want to let them in on some days. Until now that wasn't possible. With Object Fingerprint, it is.
The problem
A key can't be switched off.
Lose one key and every lock it opens is at risk.

How it's solved today, and what we do instead
Today
Rekey everything
New locks and new keys for the whole building, after every lost key.
Today
Switch to cards or chip keys
New hardware on every door, and a card, chip or battery for every user.
Object Fingerprint
Fit only the doors that matter
Swap the cylinder on the few sensitive doors. Every key in every pocket stays the same.
What you can do
Switch off
A lost key stops working in one click.
Set times
The cleaner gets in on Tuesday mornings only.
See who
Every door opening is logged by name.
Approved keys open. Blocked keys don't.
Who it's for
Organisations with big mechanical key systems and a few sensitive doors: campuses, labs, server rooms and archives. Many people, many doors, a handful that really matter.
How we compare
| What it checks | Cost grows with | Battery in the key | New wiring | Spots a copy | |
|---|---|---|---|---|---|
| Restricted key profile | who can buy a blank | — | no | no | no |
| Stamped serial number | a number stamped on the key | — | no | no | no, the copy carries it |
| Electronic key cabinet | a tag on a cable tie | users | no | no | no |
| Chip keys (CLIQ) | a chip in the key | users | yes | every cylinder | prevents copies, can't spot them |
| iLOQ | a chip in the key | users | energy harvested | every cylinder | prevents copies, can't spot them |
| Smart locks & cards | a phone or a card | users | n/a | every door | n/a, no key left |
| Object Fingerprint | the key itself | doors | no | depends on the door | being tested now |
Their cost grows with every user, ours with the doors you protect. Three employees and one entrance? Chip keys are the right answer, and we'd say so.
